Abstract
One embodiment of the invention includes a preamplifier system for a magnetic disk-drive. The system comprises a read amplifier configured to generate a read signal corresponding to data that is read from a magnetic disk via a magneto-resistive (MR) read head. The system also comprises a gain control amplifier that is configured to amplify the read signal based on a digital gain value to generate an amplified read signal. The system further comprises a feed-forward automatic gain controller (AGC) configured to set the digital gain value based on an amplitude of the read signal.
